Question 1

Which of the following statements best describes the role of a host-based firewall in endpoint security?

Options :

A : A host-based firewall only protects against malware infections on the endpoint by scanning downloaded files.

B : A host-based firewall protects the entire network by analyzing and blocking malicious traffic at the network perimeter.

C : A host-based firewall is only effective if paired with an intrusion prevention system (IPS).

D : A host-based firewall filters traffic entering and leaving an individual endpoint based on predefined security rules.

Answer: D

Question 2

An organization implements IoT devices, such as smart thermostats and IP cameras, alongside traditional endpoints, like laptops and desktops. Which of the following best describes a primary security challenge unique to IoT devices compared to traditional endpoints?

Options :

A : IoT devices are protected by advanced encryption methods, unlike traditional endpoints.

B : IoT devices require user authentication for every operation, making them more secure than traditional endpoints.

C : IoT devices often lack direct update mechanisms, increasing their vulnerability to security exploits.

D : IoT devices are isolated from network traffic, eliminating risks from external threats.

Answer: C

Question 3

A computer in a local network is configured with an IP address of 192.168.1.10 and a subnet mask of 255.255.255.0. It attempts to communicate with a web server at 203.0.113.5. What role does the default gateway play in this communication?

Options :

A : The default gateway blocks packets that are not explicitly permitted by a local firewall rule.

B : The default gateway assigns a new IP address to the computer for external communication.

C : The default gateway forwards packets destined for IP addresses outside the local subnet.

D : The default gateway resolves the domain name of the web server into its IP address.

Answer: C

Question 4

Which of the following best describes how a Security Information and Event Management (SIEM) system improves security operations?

Options :

A : SIEM tools detect malware and automatically remove infected files from endpoints.

B : SIEM tools provide log aggregation, correlation, and alerting to identify threats in real time.

C : SIEM tools replace the need for manual threat hunting by automating all security tasks.

D : SIEM tools passively collect logs without analyzing them, ensuring compliance.

Answer: B

Question 5

Which of the following best describes the responsibilities of the cloud service provider (CSP) and the customer in the Infrastructure as a Service (IaaS) cloud service model?

Options :

A : The CSP manages the underlying physical infrastructure, including networking and servers, while the customer is responsible for managing the operating system, middleware, and applications.

B : The CSP takes full responsibility for all aspects of security, including operating systems, applications, and customer data.

C : The CSP is responsible for securing the application data, while the customer is responsible for maintaining the physical hardware.

D : The CSP manages physical security and application security, while the customer is responsible for networking and hardware.
